I'm using VMware Workstation 10.0.4 with a Windows 8.1 64bit as OS on the virtual machine (and the host system). Now I am facing the problem that though the serial port is mapped into the virtual machine, it doesn't work anymore after a while and I have no clue why.
When I copy the "fresh" machine to my hdd and execute it for the first time, everything works. But after installing some things or changing os specific settings or sometimes taking a snapshot the port cannot be accessed anymore by putty. It tells me that it is unable to open the serial port but VMware shows that the port is still connected with the virtual machine. If I disconnect the port and try it on the host computer, everything works.
What did I try so far:
- Reboot virtual machine
- Reboot host system
- SerialPort disconnected and reconnected in the virtual machine
- Reset the VM, same problem after a while
Can anyone give me a hint how to solve this problem?
